Emotionally charged events are specifically those from which the most clear and detailed autobiographic memories stem. Certainly, there is a significant difference between preserving memories of pleasant events from those that are unpleasant. This is the phenomenon which enables people to retain and remember pleasant events in greater quantity than those marked as unpleasant and which is called positivity effect. According to many theories, its main purpose is retaining a positive self-image, a positive perception about life and to enable easier coping with one's past, present and future. Positivity effect is most commonly associated with older population on which it has been widely researched and proven. As opposed to older population, recognizing such phenomenon in young adults is still in question, more specifically, many researchers still cannot agree on whether such effect occurs in younger population. The aim of this research is to investigate the existence of positivity effect in young adults, moreover, to examine whether there is a difference in tendency to remembering events marked as pleasant to those marked as unpleasant, in favour of pleasant ones in younger population and to investigate whether a correlation between life satisfaction and (un)pleasant evaluation of events exists. 266 respondents of both sexes (NM=65, NF=201) participated in the research and evaluated their life satisfaction on the Likert’s type scale and wrote down ten memories from their life which they evaluated on a scale of pleasure ranging from one to seven through an online questionnaire. The results showed a different frequency of pleasant, as opposed to unpleasant events, in young adults. Young adults have recalled pleasant events significantly more, as opposed to unpleasant. A low correlation between satisfaction with life and (un)pleasant evaluation of events has also been determined; those more satisfied with their life, recalled pleasant memories more than those who evaluated their life satisfaction as bad.
